Spin Correlation and Quantum Entanglement of Fermion Pairs in Transversely Polarized Collisions
Yi-Jing Fang, Amit Bhoonah, Kun Cheng +3
We systematically study the spin correlations and quantum entanglement in transversely polarized electron-positron collisions. We find that the -channel QED process $e^-e^+\to f…
Galactic magnetic fields seeded by ultralight dark photons
Joshua Berger, Amit Bhoonah, Joseph Bramante +3
In this work, we show that ultralight dark photons, which couple to the Standard Model photon through kinetic mixing, can potentially source galactic scale magnetic fields. Althoug…
The NANOGrav 15 yr Data Set: Piecewise Power-Law Reconstruction of the Gravitational-Wave Background
Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +108
The NANOGrav 15-year (NG15) data set provides evidence for a gravitational-wave background (GWB) signal at nanohertz frequencies, which is expected to originate either from a cosmi…
A Baryon and Lepton Number Violation Model Testable at the LHC
Amit Bhoonah, Francis Burk, Da Liu +2
Proton decay experiments typically constrain baryon number violation to the scale of grand unified theories. From a phenomenological point of view, this makes direct probing of the…
Sub-MHz Radio Background from Ultralight Dark Photon Dark Matter
Javier F. Acevedo, Amit Bhoonah, Kun Cheng
Dark photons are a well-motivated candidate for dark matter, but their detection becomes challenging for ultralight masses with both experimental and astrophysical probes. In this…
Right-Handed Neutrino Masses from the Electroweak Scale
Brian Batell, Amit Bhoonah, Wenjie Huang
Heavy right-handed neutrinos are highly motivated due to their connection with the origin of neutrino masses via the seesaw mechanism. If the right-handed neutrino Majorana mass is…
